On one of my PCs, Resharper does not show action list when caret is on some symbol (like on class name) or any error / suggestions. It always shows only generic "action search" where there are no context actions available (ie. Create constructor, move class to dedicated file, ...)
I have the same latest version of Visual Studio (16.8.2) and Resharper (2020-09-25) on both PCs i use.
This is very annoying for me as i am heavy user of those context alt+enter actions.
